Overview
L' Ambient 17 Click Board™ est une carte complémentaire compacte utilisée pour mesurer la quantité de lumière ambiante présente. Cette carte est équipée du TSL2572, un capteur de lumière ambiante à sortie numérique avec une interface I2C d'AMS AG. Le TSL2572 peut détecter une large plage d'éclairement jusqu'à 60 klx et offre une excellente réactivité proche de la réponse de l'œil humain. Il est conçu pour contrôler la luminosité dans diverses applications en fonction de la disponibilité de la lumière ambiante, de la luminosité pour une visibilité optimale et de l'efficacité énergétique. Le fonctionnement dans une plage de températures de -30 °C à 70 °C garantit un fonctionnement stable dans des conditions extrêmes. Cette carte Click™ est la plus adaptée pour obtenir des données de lumière ambiante afin de régler la luminosité dans les applications qui nécessitent des économies d'énergie et une meilleure visibilité.
L' Ambient 17 Click Board™ est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette Click board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Ambient 17 Click Board™ Work?
The Ambient 17 Click Board™ as its foundation uses the TSL2572, a high sensitivity light-to-digital converter that transforms light intensity into a digital output signal from AMS AG. The TSL2572 provides ambient light sensing (ALS) that approximates human eye response to light intensity under various lighting conditions and through a variety of attenuation materials. Accurate ALS measurements result from dual-diode technology and the UV rejection filter incorporated in the package. In addition, the TSL2584TSV can detect a wide range of precise lux measurements up to 60klx, even when mounted behind dark glass. It also has stable performance over a wide temperature range of -30°C to 70°C, suitable for measuring the present ambient light.
The Ambient 17 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labelled as INT, indicating when a specific interrupt event occurs, such as detecting a meaningful change in light intensity. An interrupt is generated when the value of an ALS conversion exceeds either an upper or lower threshold. In addition, a programmable interrupt persistence feature allows the user to determine how many consecutive exceeded thresholds are necessary to trigger an interrupt.
The Ambient 17 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Ambient 17 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Ambient 17 Click Board™ driver.
Key functions
-
ambient17_get_int_pin
This function returns the INT pin logic state. -
ambient17_set_atime
This function sets the ATIME register for the selected ALS integration time. -
ambient17_measure_light_level
This function reads the raw ADC data from two channels and then measures the light level in lux based on those readings.
